[0002] Die-casting molds are tools for casting metal parts, and are tools used to complete the die-casting process on a dedicated die-casting forging machine. The basic process of die-casting is: the molten metal is first cast and filled into the mold cavity at a low or high speed. The mold has a movable cavity surface, which is pressurized and forged as the molten metal cools, eliminating the shrinkage and porosity defects of the blank and making the internal structure of the blank reach the broken grains of the forged state. After the existing die-casting mold is closed, the molten metal enters the cavity and relies on natural cooling. The cooling rate is slow, which reduces the efficiency of product processing.
